Texture Game-Changer
"I have used this system daily now for the past month. I noticed a change within days. . . but the real miracle is that my husband noticed TOO! This is my forever Vit C."
Great concept, but difficult to control and prone to pilling
"I really wanted to love this product, but unfortunately it didn’t work well for me. I have a smaller face, and the amount dispensed with each pump feels excessive, which makes it seem like a lot of product is going to waste. I also experienced pilling when layering moisturizer on top. Even after waiting up to an hour to let the serum fully absorb, I still ran into the same issue, which was frustrating and again made it feel like I wasn’t getting the most out of the product. I do love the concept of the powder vitamin C for maintaining potency—it’s a great idea. I just wish there were more control over how much serum and powder is dispensed so it could be better tailored to individual needs."
I like the daily dispensing
"I like the daily dispensing of the Vitamin C for freahness and effectiveness. My hylauronic acid dispenser became dissembled and most of it spilled out. The canisters need more effective directions."
Yes! You will see the results
"My face had an irritated redness with breakouts. This serum not only eliminated the redness, but the breakouts stopped, and now the remaining marks are starting to fade. None of the typical dryness that appears with a lot of Vitamin C products."
Love this stuff, but goes too fast!
"I love the whole system and can say it's completely worth the cost, even as a skincare minimalist. I've noticed a huge improvement in my skin tone over time using this daily (and that's after ditching Skinceuticals C serum). My only complaint is that each refill feels like so little powder and is gone even before I'm able to receive my next subscription shipment. Give us a bigger refill option please!!"
Good stuff
"Good stuff"
Great vitamin C!
"I really like this vitamin C serum. I feel like I noticed a visual difference immediately. I like the smell, it was gentle, and it didn't cause breakouts. I wish it was easier to travel with, but otherwise I have no complaints!"
The serum for sensitive skin!
"I’m recovering from topical steroid withdrawal and must avoid numerous ingredients because my skin barrier is thin and damaged. At first I was afraid to try because most products irritate my skin. But this duo has dramatically transformed my skin that I cannot stop talking about it and recommending it to friends! It helps my broken skin heal quicker and gives me this glow that I have not seen from other products. I LOVE EXPONENT! 🧡"
